This year’s team is called the Fall of Fame. Four bachelor degree students from the Friedrich-Alexander-University Erlangen-Nürnberg (Germany) will perform their experiment at ZARM from 4 to 15 November. They are studying chemical and biological engineering, and they are in fourth semester.
Their campaign will take place from 4 to 15 of November at the ZARM Drop Tower facility of Bremen University in Germany. The team will have the opportunity to launch their experiment 5 times. They will use the catapult mode to obtain a microgravity period of 9.3s.
Their experiment will focus on vibrated submonolayers. In many situations, granular systems subjected to external agitation have a tendency to segregate, rather than mix. This phenomenon is of enormous importance in industrial applications. When mixtures of particles differing in size, shape or material properties are agitated, a variety of pattern formation phenomena are observed. This team would like to investigate if, as predicted by simulation results, wall friction is the main driver of strip formation on vibrated granular submonolayers. They therefore have an experiment that drives a set of granular samples, forming stripes under Earth gravity conditions and they would to see if the stripes formation is inhibited in microgravity conditions.
